I have absolutely no doubt that an experienced SwiftUI macOS developer could easily produce better UI than Claude can today. The thing is, Claude produces better UI than a replacement-level macOS developer can, and, much more importantly --- this is really the core of my argument --- \infty better UI than a typical developer can produce, because most developers don't ever build native UI.

If I'm shipping a product where each development/release cycle costs my team $5MM, I am absolutely going to spring for the professional SwiftUI developer.

But most things normal developers build in their spare time don't even cost $50 per cycle. Unless they're UI learning projects or projects by UI experts, there is no "budget" for UI. At best, for real labor-of-love projects, you get a TUI where the developer spends 5 hours of their life that they will never get back creating a 70%-functional terminal version of the affordances the native UI toolkit provides out of the box.

That's all over now. However competitive Claude-generated SwiftUI user interfaces are with expert SwiftUI projects, they roflstomp the UI options available to most developers. I can't say enough what a smoking gun the flickering Signal app is here!
